MIAMI (CBSMiami) – Miami-Dade has issued an evacuation order for people who live in mobile home parks, unsafe structures and areas prone to flooding.

The county has opened three shelters for evacuees.

In North Miami-Dade, the shelter is located at Dr. Michael Krop Senior High, 1410 County Line Road, Miami. This shelter is the only shelter that will accept pets.

In Central Dade, the shelter is located at Booker T. Washington High School, 1200 NW 6th Avenue, Miami.

In South Miami-Dade, the shelter it located at Robert Morgan Sr. High, 18180 Southwest 122nd Avenue, Miami

All three shelters are available to people with disabilities and service animals.

Mayor Carlos Gimenez and county officials recommend all residents in Miami-Dade County have three days worth of supplies for everyone in the household. Additionally, the mayor said residents who can, should put up their shutters on Saturday.

Tropical Storm Isaac has been moving faster than initially anticipated and that has shortened the time frame for everyone to get their preparations completed. Mayor Gimenez said now is the time to fill your car with gasoline.

County officials said residents need to verify if you live in an evacuation zone and be prepared to move if an evacuation is called for by the EOC. You can find out if you’re in an evacuation zone by clicking here.

Miami-Dade Metrorail and Metro Mover are in service Saturday and a decision about Sunday will be made later in the day.

Mayor Gimenez asked that people not trim trees or shrubs now and that any trash like that should be taken to trash centers which will be open from 7 a.m. to 7 p.m.

Mayor Gimenez said the Miami-Dade Emergency Operations Center is working at a Level 2, or partial evacuation, and 311 is up and running in Miami-Dade.
